Abstract (en)
[origin: WO2014067806A2] The invention relates to a method for operating an electronically commutated electric machine (2), having the following steps: Activating a driver circuit (3) in accordance with a commutation schema by switching power semiconductor switches (32, 33); applying a pulse width modulation to the switching of the power semiconductor switches (32, 33); and limiting a pulse control factor of the pulse width modulation to a pulse control factor threshold value.
